[Solved] There should be atleast one MOERA in Email Addresses.

Problem

This week I needed to remove a old domain in office 365 for a customer.

When trying to remove I received this message stating I needed to change some accounts and groups, because they still use the old domain.

In this case I needed to change 1 user and 6 groups, because they use the old domain as an alias.

Solution

This can only be done in powershell

I needed to change the PrimarySmtpAddress from 2 groups, and change the alias for 4 groups.

First check the current settings :

 

get-UnifiedGroup -Identity "GroupName" | select -ExpandProperty emailaddresses


SMTP
:GroupName@OldDomain.com

smtp:GroupName@NewDomain.com

 

You can change the PrimarySmtpAddress of a group with :

 

Set-Group "GroupName" -WindowsEmailAddress "GroupName@NewDomain.com"

 

Check again :

 

get-UnifiedGroup -Identity "GroupName" | select -ExpandProperty emailaddresses

 

smtp:GroupName@OldDomain.com

SMTP:GroupName@NewDomain.com

 

You can remove the alias of a group by :

 

set-unifiedGroup -Identity "GroupName" -EmailAddress @{remove='GroupName@OldDomain.com'}

 

Error

In this case I received an Error :

There should be atleast one MOERA in Email Addresses.

+ CategoryInfo : NotSpecified: (:) [Set-UnifiedGroup], RecipientTaskException

+ FullyQualifiedErrorId : [Server=VI1PR1001MB1007,RequestId=5f4a4103-72c8-4971-a0b5-3c111adc04c4,TimeStamp=29/10/2019 14:29:25] [FailureCategory=Cmdlet-RecipientTaskException] 237F131F,Microsoft.Exchange.Management.RecipientTasks.SetUnifiedGroup

+ PSComputerName : outlook.office365.com

What is a MOERA ?

MOERA: Microsoft Online Email Routing Address

https://docs.microsoft.com/en-us/powershell/module/exchange/users-and-groups/set-unifiedgroup?view=exchange-ps

Why is it giving this error ?

The error is thrown because the group does not have a default domain email address.

The default domain address of a tenant is XXX.onmicrosoft.com

So after the error, we know what to do :

 

set-unifiedGroup -Identity "GroupName" -EmailAddress @{add='email@TenantName.Onmicrosoft.com'}
Get-unifiedGroup -Identity "GroupName" | FL

 

smtp:GroupName@OldDomain.com

SMTP:GroupName@NewDomain.com

smtp: email@TenantName.Onmicrosoft.com

 

We now can remove the OldDomain :

 

set-unifiedGroup -Identity "GroupName" -EmailAddress @{remove='GroupName@OldDomain.com'}
Get-unifiedGroup -Identity "GroupName" | FL

 

SMTP:GroupName@NewDomain.com

smtp: email@TenantName.Onmicrosoft.com

 

The OldDomein emailaddress is now removed !
